A major problem in modern dendrochronology is that the methods traditionally used for linking tree ring growth data to climate records are not well suited to reconstructing low-frequency climatic variations. In this study, ...

Drought provokes a number of physiological changes in plants including oxidative damage. Ascorbic acid (AsA), also known as vitamin C, is one of the most abundant water-soluble antioxidant compound present in plant tissues. ...

Symbiotic nitrogen fixation is one of the first physiological
processes inhibited in legume plants under water-deficit conditions.
Despite the progress made in the last decades, the
molecular mechanisms behind this ...

Density is an important wood mechanical property and an indicator of xylem architecture
and hydraulic conductivity. It can be influenced by forest management and climate. We studied the
impact of thinning and climate ...

Accumulation of abaxial anthocyanins is an intriguing leaf trait particularly common among deeply
shaded understorey plants of tropical and temperate forests whose ecological significance is still not properly understood.
To ...

Research on cancer and other conditions has shown flavonoids and sphingolipids to be food components capable of exerting chemoprotective action. Nevertheless, little is known about their effects on healthy individuals and ...

Composting in bins is one of the most practical home composting methods. There is currently a need for greater information to improve the management of the composting process and to create home composting programs, which ...

The malnutrition caused by liver cirrhosis (LC) often worsens the course of the disease. Patients affected by LC often have a low bioavailability of the anabolic liver peptide insulin-like growth factor (IGF)-I. The present ...

A key enzyme of the shikimate pathway, 5-enolpyruvylshikimate-3-phosphate synthase
(EPSPS; EC 2.5.1.19), is the known target of the widely used herbicide glyphosate.
Glyphosate resistance in Amaranthus palmeri, one of ...

Nitrogen deposition and its ecologic effects on forest ecosystems have received global attention.
In this paper, the ecosystem model FORECAST was used to assess the effects of nitrogen
deposition on carbon sequestration ...

In the context of global climate change, it is critical to study how different forest management
practices affect forest carbon sequestration. This is especially important for forest managers
and policy makers who will ...

The glyoxylate cycle, which is well characterized in higher plants and some microorganisms but not in vertebrates, is able to bypass the citric acid cycle to achieve fat-to-carbohydrate interconversion. In this context, ...

Acetolactate synthase inhibitors (ALS-inhibitors) and glyphosate (GLP) are two classes of herbicide that act by the specific inhibition of an enzyme in the biosynthetic pathway of branched-chain or aromatic amino acids, ...

Many rural communities in British Columbia (western Canada) are at risk from wildfire. This risk will increase over time as a result of climate change because of higher average temperatures, longer growing seasons, and ...

How long would it take for forests to recover their original productivity following continuous intensive management if they are left untouched? This issue was explored using the model FORECAST, calibrated and validated for ...

Atmospheric pollution levels in China are increasing quickly. Experience from other polluted regions shows that tree growth could be affected, but long-term effects of N deposition and soil acidification on Chinese forests ...

The herbicide glyphosate reduces plant growth and causes plant death by inhibiting the biosynthesis of aromatic amino acids. The objective of this work was to determine whether glyphosate-treated plants show a carbon ...
